Multi-colored liquid crystal display device with characters not displaying shifts in positions even upon color changes

Abstract

A liquid crystal device is disclosed wherein each part of a display section exhibiting a display pattern is divided into a plurality of segments by a spacer; liquid crystals of different absorption spectra are sealed in these segments; a transparent selective electrode is disposed in each segment; and the selective electrodes are selectively made to conduct, thereby enabling a display of different colors.

We claim: 
     
       1. A multi-colored liquid crystal display device having a viewing surface comprising: at least one display section exhibiting a given display pattern, said at least one display section including a plurality of closely adjacent display segments, the spacing between adjacent display segments being from about 0.5 to about 0.1 mm and each display segment having a width of from about 0.05 to about 0.1 mm, each of said display segments exhibiting substantially the same said given display pattern and each said display segment including means for receiving liquid crystals therein;   said display segments of said at least one display section being adjacent each other in a direction substantially along said viewing surface and being so closely adjacent each other that, to a viewer, they appear to be in substantially the same position on said display device;   liquid crystals of respective different absorption spectra sealed in adjacent display segments of said at least one display section, each display segment of said at least one display section containing liquid crystals of a different absorption spectrum such that said adjacent display segments provide respective different color displays when energized; and   a source of electrical power coupled to said display segments for selectively energizing respective display segments of said at least one display section to selectively produce a display of said given display pattern in different colors without substantially changing the apparent position of said given display pattern with respect to a viewer.   
     
     
       2. The multi-colored liquid crystal display device of claim 1, comprising a plurality of said display sections, each of said display sections exhibiting a given display pattern. 
     
     
       3. The multi-colored liquid crystal display device of claim 2, wherein said given display pattern of at least a number of said plurality of display sections are line-shaped display patterns, each display section having said line-shaped display pattern comprising at least two line-shaped display segments, liquid crystals of different absorption spectra being sealed in adjacent display segments of each of said number of display sections, and wherein said selectively energizing means comprises a plurality of line-shaped electrodes arranged in a matrix form and located adjacent said display sections, the respective line-shaped electrodes being selectively energized for selectively energizing respective points of intersection of the matrix of line-shaped electrodes to produce a dotted display of a desired color. 
     
     
       4. The multi-colored liquid crystal display device of any one of claims 1, 2 or 3, wherein segments of two different colors are adapted to be simultaneously turned on in a display section to selectively produce a display of a third color by said two different colors. 
     
     
       5. The multi-colored liquid crystal display device of claim 1, wherein said display segments are elongated segments.
